The tubes that connect the kidneys to the bladder are called ureters, and the tube that connects the bladder to the outside of the body is called the urethra. Female Reproductive System Eggs, (also called ova) are stored in the ovaries. Eggs are present when a girl is born, her ovaries will contain about 2 million of them. But they only develop into mature eggs capable of becoming a baby after the girl has reached puberty. Each ovum contains genes that carry the female’s genetic information. Two oviducts, (also called fallopian tubes) transport the ovum from the ovary to the womb, (also called the uterus). The oviducts have delicate fronds that waft the ovum along. If the ovum is fertilised, it happens in the oviducts. The uterus is a muscular sack, about the size of a small orange. This is where a fertilised ovum will develop into a baby. The neck of the uterus, (also called the cervix) is a muscular opening at the base. The cervix leads to the vagina. This is the birth canal and the place where sperm is deposited during intercourse. Male Reproductive System Sperm are produced in the testes, up to 1,000 per second. The sperm are stored in the epididymis. Sperms carry the male’s genetic information. During intercourse, sperms travel along two sperm tubes to another tube called the urethra. On the way, the prostate gland and the seminal vesicle provide fluids to nourish them and to swim in. The mixture of sperms and fluids, called semen, then passes out through the urethra. 200 to 600 million sperms may be deposited in the woman’s vagina during intercourse, but most of them will never reach the ovum, and only one of them will actually fertilise it.
